Technical Field
[0001] The utility model belongs to the technical field of four-way vehicles, in particular to an up-and-down moving device for a cargo fork of a four-way vehicle. Background Art
[0002] In today's society, with the continuous advancement of technology and the improvement of industrial automation, four-way carts, as an important logistics handling equipment, are becoming increasingly widely used across various industries. Demand for four-way carts is particularly increasing in places with limited space and restricted working environments, such as warehouses, workshops, and laboratories. However, precisely because of the unique characteristics of these working environments, people are placing higher demands and challenges on the structural design of four-way carts.
[0003] Among these requirements, the most critical one was to minimize the overall size of the four-way vehicle while ensuring it could properly perform its basic functions. This design goal was to enable the vehicle to operate more flexibly in confined spaces and avoid unnecessary interference and impact on the surrounding environment during transportation. Therefore, how to minimize the size of the four-way vehicle while meeting its functional requirements became a key challenge for the designers. Utility Model Content

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.
[0018] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, it can mean a fixed connection, a detachable connection, or an integral connection; it can mean a mechanical connection or an electrical connection; it can mean a direct connection, an indirect connection through an intermediate medium, or internal communication between two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood based on specific circumstances.
[0019] See also Figures 1 to 3 In this embodiment, a four-way vehicle fork up and down movement device mainly includes a frame 1, a lifting gear box connecting plate 2, a slide rail 3, a slider 4, a lifting beam 5 and a lifting gear box assembly 6. The slide rail 3 is composed of a plurality of linear slide rails in the vertical direction, and a slider 4 is installed on each linear slide rail. There are two lifting beams 5 and two lifting gear box assemblies 6, that is, each lifting gear box assembly 6 drives a lifting beam 5 to perform up and down movement. Among them, a lifting gear box connecting plate 2 is provided on the outer side of each lifting gear box assembly 6, and the lifting gear box connecting plate 2 is installed on the vehicle frame 1. The two lifting gear box connecting plates 2 are parallel to each other, and a plurality of grooves 2-1 for installing the slide rail 3 are provided on the outer side wall of each lifting gear box connecting plate 2. The depth of the groove 2-1 is less than the thickness of the slide rail 3, and the width of the groove 2-1 is greater than the width of the slide rail 3. The outer side wall of the slide rail 3 is fixedly connected to the lifting beam 5.
[0020] This embodiment features a special design on the outer sidewall of each lifting gearbox connecting plate, creating several grooves specifically designed for mounting the slide rails. This allows the slide rails to be installed directly within these grooves, replacing the guide seats required in traditional technology. This approach not only simplifies the structure but also significantly reduces the need for guide seats, thereby reducing material costs and assembly complexity.
[0021] Furthermore, this embodiment considers the connection method between the slide rail and the lifting beam. The outer wall of the slide rail is directly fixed to the lifting beam. Compared with traditional technology, this design further saves the use of the slider base. This direct connection method not only improves the stability and reliability of the structure, but also reduces the number of parts required during assembly, thereby simplifying the assembly process.
[0022] This design optimization not only improves the overall compactness of the four-way vehicle but also significantly reduces manufacturing costs. It also simplifies the assembly process, making the vehicle more flexible and efficient in confined spaces. This design not only improves production efficiency but also enhances the device's performance, enabling it to excel in a variety of complex environments.
[0023] In this embodiment, the outer side and outer side wall both refer to the side away from the center axis of the four-way vehicle. The depth of the groove 2-1 refers to the distance from the groove opening to the bottom of the groove cavity, while the width of the groove 2-1 refers to the distance between the two parallel side walls of the groove cavity. The thickness of the slide rail 3 refers to the distance between the two parallel surfaces of the slide rail 3, which are two surfaces parallel to the bottom of the groove cavity.
[0024] The lifting gearbox connecting plate 2 consists of a first lifting gearbox connecting plate and a second lifting gearbox connecting plate of identical structure. The first lifting gearbox connecting plate has a first groove and a second groove. The first groove houses a first slide rail 3-1, on which a first slider 4-1 is mounted. The second groove houses a second slide rail 3-2, on which a second slider 4-2 is mounted. The groove 2-1 is a rectangular groove, ensuring that the slide rail 3 can be easily mounted on the lifting gearbox connecting plate 2.
[0025] The matching surface of the slide rail 3 and the slider 4 is a curved surface 3-3. This design improves the interaction between the two and enhances the efficiency and stability of the entire lifting system. This structural design ensures that the lifting beam 5 moves up and down smoothly and steadily during the lifting process, thereby improving the performance and reliability of the entire equipment.
[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention are included in the scope of protection of the present invention.
